Insufficient machining accuracy of mechanical equipment: There are many reasons for the insufficient machining accuracy of mechanical equipment, such as the insufficient machining accuracy of the fluorine rubber seal itself. These reasons are easy to attract our attention and are easy to find. But sometimes the machining accuracy of mechanical parts is not enough. These reasons are not easy to attract our attention.

Many mechanical equipment must have the shadow of fluorine rubber sealing ring, so what are the factors that endanger the application efficiency of fluorine rubber sealing ring?

Insufficient machining accuracy of mechanical equipment: There are many reasons for the insufficient machining accuracy of mechanical equipment, such as insufficient machining accuracy of fluorine rubber seals. These reasons are easy to attract our attention and are easy to find. But sometimes the machining accuracy of mechanical parts is not enough. These reasons are not easy to attract our attention. For example: pump shaft, coupling, pump casing, sealing cavity precision is not enough. The occurrence of this reason is very unfavorable to the actual sealing effect of the fluororubber seal ring.

Excessive vibration: Excessive vibration of the fluorine rubber sealing ring will eventually cause the loss of the actual sealing effect. However, the cause of the large vibration of the fluororubber seal is usually not the fluororubber seal itself. Some other parts are considered to be the root causes of vibration, such as unscientific equipment design, production and processing reasons, insufficient rolling bearing accuracy, etc., Axial force and other reasons.

The sealing surface of the fluorine rubber seal must have a certain specific pressure to play a sealing role. This requires a certain reduction in the torsion spring of the fluorine rubber seal to give the inner hole of the fluorine rubber seal a rotating power. Make the sealing surface produce a specific pressure specified for the seal.

There is no auxiliary flushing system software or the configuration of the auxiliary flushing system is unscientific: the auxiliary flushing system software of the fluorine rubber seal is very critical. The software of fluorine rubber sealing ring auxiliary flushing system can reasonably maintain the sealing surface, and has the functions of refrigeration, lubrication and flushing impurities.

Sometimes the designer is not effectively equipped with auxiliary flushing system software, which can not achieve the actual effect of sealing. Sometimes although the designer has developed the auxiliary system software, the total flow rate and working pressure of the flushing fluid are insufficient due to the residue in the flushing fluid., Flushing port design is not scientific and other reasons, but also can not achieve the actual effect of sealing.
